Hey Guys
I'm still working on this problem.
I found another article (KB1011647) which did'nt worked for me.
So I left the domain with the vCenter server and both hosts what solved to problem.
If I rejoin the domain with the vCenter server the problem occour again.
I also rejoined the domain with one of the hosts and this seems to be ok, so the problem just occur if the vCenter server is a member of a/my domain.
Could there be some other reasons as just the time configuration?
Regards
Patrick
